I’m 17 but I’m trying for a baby am I crazy?

So basically before everyone goes and judges me, I’m 17 yes, but I’m also moved out with my fiancé ( Since April 2018) engaged (Wedding March 2019), 3 months into a 9 month program to get my medical assisting. I work part time as a nursing assistant, and he makes good money. We talked about it and we both want to be young parents. We finically figured stuff outs, and I don’t mind being pregnant at my wedding. I grew up with my parents as a role model and my mom was 4 months pregnant and 17 at her wedding... I’m not aiming for that exactly it’s just a little comforting to know it’s possible (My parents are still together). I will be 18 in June 2019.
